SPECIFICATION forming part of Letters Patent No. 516,932, dated March 26, 1894.

Application filed December 1,1893. Serial No. 492.449. (No model.)

T0 at whom it may concern:

Be it known that I, ALBERT G. HOTOHKISS, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Machines for Forming Wrappers or Blanks ofPaper and Metal Foil Pasted Together, of which the following is a specification.

The invention relates to improvements in machines for forming wrappers or blanks of paper and metal foil pasted together, and comprises a machine embodying in its construction means for feeding thereto from independent rolls and in a continuous manner a strip of paper and a strip of the foil, means for automatically applying to one side of said paper an adhesive substance, means for r011 ing the foil against said side of said paper, and means for severing the composite strip of paper and foil into uniform lengths or blanks adapted for wrapping purposes. The said machine comprisesnovel mechanism for applying the paste or adhesive substance to the 'paper in parallel lines or rows instead of covering the entire surface of the paper with the paste; also means for smoothing the paste and removing any surplus thereof, prior to the contact of the foil with the paper, and also novel cutters by which thecomposite strip of foil and paper may, as rapidly as it leaves the pressure'rolls and is thereby formed, be severed into the .lengths or blanks for wrappers. v

The said machine further comprises novel features of construction, all as hereinafter more fully described and pointed out in the claims.

The object of the invention is to produce a machine which will automatically and with great rapidity form and discharge the paperand-foil blanks or wrappers of uniform size, in perfect condition and ready for immediate use for the purposes for which they may be adapted.

The invention will be more fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which-- Figure 1 is a side elevation of a machine constructed in accordance with and embodying theinvention. Fig. 2 is a vertical longitudinal section of same, the stripof paper passing through the machine being illustrated by a solid line and the strip of foil by a dotted line. Fig. 3 is a front elevation, partly in section, of same, and showing by the dotted line 22. the section on which Fig. 2 is made. Fig. 4 is a rear elevation of same. Figs. 5 and 6 are detached side elevations'of certain plates hereinafter referred .to, which plates form parts of the machine and afford means for adjusting the shafts of certain rbllers also hereinafter referred to. Fig. 7 is a detached vertical longitudinal section on an enlarged scale of the cutters or that portion of the machine by which the composite strip of paper and foil is severed into pieces, blanks or wrappers of uniform size. Fig. Sis adetached view of one of the severed pieces of the composite strip, the dotted lines indicating the rows of paste. Figs. 9 and 10 are respectively enlarged edge and side elevations of the revoluble part of the cutting mechanism by which the composite strip of paper and foil is severed into uniform pieces or blanks. Figs. 11 and 12 are side and edge elevations respectivelyof the stationary part of said cutting mechanism; and Fig. 13 is a vertical section of same on the dotted line 13-13 of Fig. 11.

In the accompanying drawings A, B, respectively, designate the strips of paper and foil which are to be pasted together to form a composite strip, and then severed into the pieces, blanks or'wrappers C of uniform dimensions. Thestrip of paper A is fed from a roll, not shown, mounted upon any suitable reel which will revolve and permit the feeding out of the paper to the machine, the end of the strip of paper being, as illustrated in Fig. 2,brought around the shafts or rollers D, D, and thence carried around the front side of the main cylinder or drum E, whence the paper passes to the rear end of the machine between the pressure rollers F, G, and cutters H, I, the latter operating, as hereinafter described, to sever the composite strip of paper and foil into its lengths or blanks. The tin foil B is fed from a roll, not shown, and passes around the shafts or rollers J, as shown in Fig. 2, and between the small pressure roller F and roller F, around the front side of which it passes and thence extends between the rollers F, G, and upon the upper surface ICO of the strip of paper A, the strips of paper and foil passing together in face to face contact between the said rollers F, G, and thence moving between the cutters H, I, as indicated in, Fig. 2. The pressure of the rollers F G on the foil may be regulated by the usual adjusting screws W.

The main cylinder or drum E is mounted upon the shaft K which carries upon one end the gear wheel L (see Fig. 1) whose teeth are engaged by the pinion M mounted upon the shaft N, which receives its motion from the gear wheel 0, pinion P, driving shaft Q and driving Wheel R. The power imparted to the power wheel R or to the hand wheel R at the opposite side of the machine, see Fig. 4, is transmitted through the shaft Q and pinion P to the gear wheel 0 and shaft N, whence said power is communicated through the pinion M to the gear wheel L and shaft K, whereby the drum E receives its revolving motion in the direction of the arrow shown in Fig. 2. The motion of the gear wheel L is communicated through the gear wheel S to the gear wheelT mounted upon the shaft T of the lower pressure roller G, and this gear wheel '1 engages the gear wheel V mounted upon the shaft of the upper pressure roller F, whereby the motion of the rollers F, G, toward each other is secured. The shaft T also carries a smaller gear wheel T which through the intermediate gears W, X, communicates motion to the gear wheel Y mounted upon the end of the shaft Z, forming a part of or secured to the upper revo lublecutterbarH,which,or the shaft of which, at its end opposite to the gear wheel Y is provided with the balance wheel 19.

Over the main cylinder or drum E is mounted in suitable bearings the transverse shaft 0 upon which are secured the pressure or guide rollers cl in position to impinge upon and aid in the feeding forward of the strip of paper A. The rollers d contact with the paper A at points between the rows of paste e which are applied to said paper as illustrated more clearly in Fig. 3, and hence the paste does not come into contact with the said rollers d. The extent of the-pressure of the rollersd upon the paper A will be regulated by a set screw f.

At the front end of the machine is provided the mechanism by which the rows of paste are applied to the paper A, and at the opposite end of the machine is provided the mechanism by which the composite strip of paper and foil is severed into lengths.

Upon reference to Fig. 3 it will be noticed that the entire surface of the paper A is not covered with the paste but that the latter is applied in rows lettered e. The mechanism for applying the paste to the paper consists of the receptacle 9 for the liquid paste, the rings h. which enter the paste and are carried between the collars t on the shaft j, the small intermediate rubber rollers mounted on the shaft m, and the larger contact rollers 72 mounted on the shaft 0, the bearings of the latter shaft being supported by the set screws g by which said shaft may be adjusted vertically as desired and thus regulate the pressure between the rollers 01., k and h. The ends of the shaft m of the rollers 70 are mounted in vertical guides is, as shown in Fig. 2. The rings h rest in grooves between the collars 71, as illustrated in Figs. 2 and 3, and are sufficient in thickness to extend upward above said collars and engage the periphery of the rollers 7a, which about equal in width the said rings h and also the rollers 71 with which they are in contact.

During the operation of the machine the rings 72 are caused to have a revolving motion owing to the pressure exerted on them by the rollers 70, and during this revolving motion the said rings h carry upward the paste from the receptacle g, the said paste transferring itself to the rollers 70 and thence to the rollers 01., the peripheries of which press against the paper A as it is being fed over the revolving drum E, and. deposit the rows of paste 6 thereon. The shaft j is journaled in the side frames of the machine, and the shafts m, 0, are mounted in the L-shaped frames 0" which are connected by the transverse rod 8 and pivotally mounted on bushings at the ends of the shaft j. The rollers n are adjusted with respect to the 'main cylinder or drum E by means of the set screws 25 which pass through the sleeves to and are provided with the lock nuts y. Thesleeves w are formed or provided with the transverse sleeves 1 in which are the eccentrics y" mounted on the shaft y, which is mounted in the side frames of the machine, as indicated in Figs. 1 and 3, and has on one end the handle a (see Figs. 1 and 3) by which the shaft may be turned to move the eccentrics upward from the position shown in Fig. 2 and to return the eccentrics to the position shown in Fig. 2, without at either time disturbing the adjustment of the screw t and nuts y. The handle a carries a screw A and not B, the former adapted to slide in the groove of the segmental guide 0' when the handle is moved, and the nut B being to secure the handle in any desired position. The segmental guide 0' is fastened by means of screws to the side frame of the machine, as indicated in Fig. 1. The object of the screws t and nuts y is to secure the proper adjustmentof the rollers n with respect to the drum E in accordance with the thickness of the paper A, and the purpose of the handle a and eccentrics y" is to enable the attendant, Without affecting the screws t and nuts y, to draw the frames 'r'sufficientl y forward to afford a proper space between the drum E and rollersn for theinsertion of the end of the strip of paper A when the latter is being introduced to the machine. When the handle a and eccentrics y" are in the positions shown in Figs. 1 and 2, the rollers 97. will be in close contact with the paper A, and when the handlea is turned downward along the guide 0' the shaft 31 will be this will have theeffect of drawing the frames 0" slightly forward (or to the right, looking at Fig. 2) and thus relieving the rollers n from the drum E a sufficient distance to admit between the rollers and drumthe end of the strip of paper. lVhen the handle a is turned downward it may besecured by the nut B; and after the paper has been passed between the rollers 12 and drum E and beneath the rollers 01, the nut B will be loosened and the handle (1 moved upward again to position, where it will be secured by tightening the nut B. The result of moving the handle a upward, as just stated, is to return the eccentrics y to the position shown in Fig. 2 and thus lower the sleeves to and move the frames rand rollers n inward toward the "drum E.

As shown in Fig. 1, the shaft of the rollers n receives its motion from the gear wheel L and pinion D, and the shafts j, m, receive their motion from the gear wheel L through the intermeshing gears E, F, and G. The gears E and F are secured by screws and nuts to the plate H, see Figs. 1 and 5, which is swung on the end of the shaft jand fastened by a nut I to the side of the machine frame. The plate H is provided with the slots shown in Fig. 5 to permit the accurate adjustment of the gears E, F, with the gear wheel L and gear wheel or pinion G; or a change, if desired, in the'sizes of the gears E, F.

At a point intermediate the rollers cl and paste rollers n, the rod J extends transversely between the sides of the machine and carries the flexed springs K having on their lower ends the soft wipers L, which are in line with the rows (2 of paste and have apressure against the paper A moving over the drum E. The wipers L operate to remove or hold back any surplus paste that may be carried upward by the paper and to smooth and render uniform the rows e of the paste. I

In the rear of the pressure rollers F, G, is the table A, upon the rear face of which is secured by screws or otherwise the stationary cutter-bar I, which is novel in respect to the form of its cutting edge in that said edge, as clearly illustrated in Figs. 11, 12 and 13, is scalloped its entire length, forming the series of equi-distant pointed edges M extending across the width of the bar. At a suitable point in the rear of the stationary cutter I is mounted by means of the shafts Z the revoluble cutter-bar H, whose cutting edge N is, as illustrated in Figs. 9 and 10, formed with the series of inclined or shear-edges O. The bar H has a revolving motion,- as above described, and with each revolution the cutting edge N of said bar co-operates with the cutting edge of the bar I to sever a length of the composite strip of paper and foil, as indicated in Figs. 2 and 7. In Fig. 2 the composite strip of foil and paper is shown as being fed between the cutters H, I, the cutter H revolving toward the cutter I, and in Fig. 7 on an enlarged scale the position of the cutter H shown is the one it assumes u'pon cutting the blank 0 from the'composite strip. The timing of the motion of the cutter-bar H is important in that said motion regulates, to a degree at least, the length of the blank or wrapper 0 to be severed from the composite strip of foil and paper. With each revolution of the cutter bar H one blank or wrapper O is severed from the composite strip and falls upon the incline P, down which it passes to a suitable table or other receiver, not shown. The timing of the revoluble cutterH may, of course, be effected by the size of the gear wheels T, W, X and Y, and to permit the ready adjustment of said gear wheels (and a change in the size of same when desired)'I have provided'a plate Q (see Figs. 1 and 6) which is swung from the shaft T, may be adjustably set by the nut Q, and is provided with theslots shown topermit theindependent and ready adjustment of the gears W, 'X,'0r the substitution of larger or smaller gears for those lettered W, X, in a well known manner. I regard the form of the cutting edges'of the cutters H, I, as of special importance in that they effectually sever the composite strip in a regular manner without inj ury to either the foil or paper and with great rapidity. The bar 11 has a shear cut and operates upon the strip at equi-distant points,its edges 0 forming a series of cutting edges operating in'unison but on independent portions of the strip. The bar I, as above described is formed with the series of pointed edges M, and these on the contact of the bar H with the strip, penetrate the latter before the severing of the blank or wrapper has been completed, and hence the blank or wrapper is not by one blow chopped from the strip but bya gradual cut extending across its width, is quickly sheared from the strip without disturbing the latter or in any way distorting the blank or its component parts.

It will be observed that the feeding of the composite strip between the rollers F, G, is

continuous, and hence when the bar H is descending, as .in the act of severing a blank or wrapper, some provision should be made to preventthe edge of the strip left after the blank or wrapper has been removed from'riding upward over the bar H, and to this end I have provided the said bar with the groove X into which the end edge of the strip will feed and which will during the continued downward motion of said bar carry the said edge of the strip downward and insure the continued feeding of the strip between the cutters H, I.

The operation of the machine will be understood' from the foregoing description, in which the functions of the parts are explained in connection with the description of their construction. It may be stated, however, that when power is applied to the belt wheel R or hand wheel R motion will be imparted from the shaft Q through the gear wheels IIO P, O, shaft N and pinion M to the gear wheel L, which not only causes the revolution of the shaft K and drum E, but through the gear wheels D, E, F and G, sets in motion the paste rollers 71,70 and n, and through the gear wheel S and gear wheels T, V, also sets in motion the rollers F, G. The revolution of the shaft T carrying the gear wheel T is communicated through the gear wheels T, W, X, and Y to the cutter-bar H, whereby the latter receives its revoluble motion.

The strips of paperA and foil B having been passed into the machine and the latter having been set in motion, the feeding of the strips of foil and paper will continue uninterruptedly, the paper receiving the rows of paste and the foil thereby attached thereto, whereby the composite strip will be formed and passed between the cutters H, I, which sever the same into predetermined lengths or blanks suitable for wrappers. The strips of paper and foil may or may not equal each other in width as may be desired, and in the present instance I have shown the foil as being less in width than the paper, thus leav ing an exposed paper edge, as shown in Fig. 8, which may be folded inward in the process of wrapping and covered by a label or stamp as may be desired.

It will be observed that the paste does not entirely cover the surface of the paper, and

this is desirable in that there is no unnecessary waste of paste incurred or increased thickness applied to the paper, nor is there any liability of the moisture of the paste shrinking or distorting the paper. The blank or wrapper produced being free of any excess of paste is pliable, may be easily folded and will not be liable to crack or break when in use.

The revoluble cutter H is mounted in bearings a, which are adjustable toward or from the cutter I by means of screws 1)".
